For this animation I used a dynamic paint canvas on a plane that emits hair particles based on a wet map. I used another particle system as the dynamic paint brush

For this animation I distributed instances of a box on instances of a bezier circle and delayed their appearance by animating their scale

For this animation I used the distance node from the animation nodes addon to change the height of the boxes based on their distance to an empty.
